    • Asteroseismology of PG 1541 + 651 and BPM 31594 with TESS 

      Romero, Alejandra Daniela; Rosa, Gabriela Oliveira da; Kepler, Souza Oliveira; Bradley, Paul A.; Uzundag, Murat; Bell, Keaton; Hermes, James J.; Ramos, Gabriel Lauffer (2023) [Journal article]
      We present the photometric data from TESS for two known ZZ Ceti stars, PG 1541 + 651 and BPM 31594. Before TESS, both objects only had observations from short runs from ground-based facilities, with three and one period ...

    • Discovery of 74 new bright ZZ Ceti stars in the first three years of TESS 

      Romero, Alejandra Daniela; Kepler, Souza Oliveira; Hermes, James J.; Amaral, Larissa Antunes; Uzundag, Murat; Bognár, Zsófia; Bell, Keaton; Vanwyngarden, Madison; Baran, Andy; Pelisoli, Ingrid Domingos; Rosa, Gabriela Oliveira da; Koester, Detlev; Klippel, Theylor Schumacher; Fraga, Luciano; Bradley, Paul A.; Vuckovic, Maja; Heintz, Tyler M.; Reding, Joshua S.; Kaiser, B. C.; Charpinet, Stéphane (2022) [Journal article]
      We report the discovery of 74 new pulsating DA white dwarf stars, or ZZ Cetis, from the data obtained by the Transiting Exoplanet Survey Satellite mission, from Sectors 1 to 39, corresponding to the first 3 cycles. This ...

    • Kepler and TESS observations of PG 1159-035 

      Rosa, Gabriela Oliveira da; Kepler, Souza Oliveira; Córsico, Alejandro Hugo; Costa, Jose Eduardo da Silveira; Hermes, James J.; Kawaler, Steven D.; Bell, Keaton; Montgomery, Michael Houston; Provencal, Judith L.; Winget, Donald Earl; Handler, Gerald; Dunlap, Bart; Clemens, J. Christopher; Uzundag, Murat (2022) [Journal article]
      PG 1159-035 is the prototype of the PG 1159 hot (pre-)white dwarf pulsators. This important object was observed during the Kepler satellite K2 mission for 69 days in 59 s cadence mode and by the TESS satellite for 25 days ...

    • Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with TESS : II. Discovery of two new GW Vir stars: TIC 333432673 and TIC 095332541
